In the calendar.tsk you have to set cget1 to your login information. You will also need to change the variable set %WORK, Work if %CTITLE ~ Work to whatever you put in the "what" section of your google calendar event.

I have modified it heavily for my use and what I want the clock to say. This profile runs every 15 minutes but only annouces the time on the hour and half hour.

I broke the talking clock into 2 profiles. 1 sets the time and the other does the talking that way I can use the voice part on other profiles.

The variable %BREAK in Say Time.tsk should be set a half hour before your break starts. It is default set to 08.30/10.30/13.00/15.00/10.30L

This means that my breaks are at 9am 11am 1:30pm 3:30pm. The 10.30L denotes my lunch time. Breaks are 15 minutes and lunch is half hour. The 3:30pm is quitting time and it is always nice to know you have 10 mintues left in your day. :D

The main action for the breaks comes from Zzz - Work - 1.tsk. Here we set the break variables

I use Loquendo and you may have to change action 4 in voice.tsk. You will also notice in voice.tsk that the %SAYTEXT is done from the alarm stream. I did this so when I am listening to music it will be clear and understandable. Also note if the %HEADSET =1 section there are two alarm volumes set. If I am using earbuds I do not want the volume to be max, but if I am using the AUX jack then I do not mind.
